I have to say that this is one of the worst xin guides i've seen in a long time. The first mistake is the build items, the only items that gives att speed is the yomuu and trinity and due to this xin can pump out enough dps but he cant benefit enough from his w's passive healing effect. The second mistake is the masteries, looking closely it is physically impossible to achieve them. It's labelled as 21/9/0 but if you want to achieve the masteries you have set you need 22/12/0 due to two masteries selected that are not available till the one behind it is mastered. The third mistake is the threat levels of champions, the enemy champions selected are grossly underestimated and can easily destroy xin in the early stages. Lee sin is a much higher threat level than amumu, Jarven and Warwick are also a more difficult threat as well

Great guide!

I tested it, its a good option, im going to add it to the guide thank you very much :)

You should maximize an ability at level nine because at level nine you'll have one really strong ability instead of some abilities having just awful base damage due to being skilled randomly.

Enchanted Armor is awful as a mastery because even with 100 amor it just provides you 5 armor.
You cannot select Bladed Armor without selecting Tough Skin . Personally, I'd prefer going for Tough Skin only and putting three point into Block + Unyielding to improve your defensive stats when ganking.

Corrected a lot of mistakes and im going to add strategies for teamfights

yes, im argentinian and my english its horrible, thank you for your advice! ima start correcting and revising :)

The huge number of mistakes in your guide is making me nauseous: I have nothing againts grammar mistakes, but atleast take the time to type the letters in the good order.

Take a look at the BBCODE Guide and open a dictionnary.

In terms of strategy and advices: its decent.
